Thank you for the detailed information on the topic. Performance issue on my POC setup was the main reason to open this topic. As I got clarity on most of the things you have explained, I will point out areas where I need more info and you asked for clarity.
mjumper wrote > What do you mean by "CPU choking"? In my POC setup I observed that more than 100 concurrent user interaction triggers high CPU usage in guacamole server. This higher usage remains even after closing most of the remote console browser tabs (as of now I dont have the exact figure). In these situations, guacd service restart brings the CPU usage to normal. It was like closing of active consoles didnt free up the CPU resource. As I dont have an automated test setup to generate large number of users, I relied on an experimental POC setup load, which dont have a huge number of concurrent users all the time for a consistent testing. As you mentined about the use of Sikuli to generate concurrent user load, I have to look into it. > I'm not sure what you are referring to by consoles with rich UI or media. I was referring to Video with sound content mainly. Is there any difference between GUI and Terminal console in resource consumption? > If you are expecting all users to constantly watch video at the same > time.. Yes I am expecting that kind of usecase and I want the Guacamole setup to handle that. Speaking of 400-500 users with active user count goes beyond 200. These users will be mostly accessing UI consoles compared to Terminal. So I am more concerned about Guacamole server configuration which can support this much concurrent load. Need to plan future scalability options as well. If I have a performance matrix for a given hardware spec, I could set proper scale up threshold for application level Guacamole load balancer to handle future load as well, Need more info on load balancing methods I can try on Guacamole server. Planned deployment environmnet is AWS EC2. About Tomcat thread, with my initial tweaks I didnt observe any dramatic change in performance with low number concurrent user count. I have to check more into this. -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/ --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
